GNC AMP Mass XXX Muscle Building and Workout Support Protein Powder | Chocolate | 13 Servings

GNC AMP Mass XXX is a clinically proven strength and mass gainer that combines high-quality protein powder, key nutrients, and science-backed innovations to fuel proven results and performance. The product's macronutrient blend delivers 50g of protein, including naturally occurring essential amino acids, plus carbs and healthy fats, and it's clinically proven to help get better results out of workouts, with the potential to increase lean muscle mass with 40% fewer sets.*

At the core of Mass XXX is MyoTOR, a clinically proven ingredient that can accelerate improvements in strength in as little as 2 weeks of training. Additionally, the formula contains BETAPOWER, a patented betaine anhydrous clinically dosed to support power and enhance athletic performance. The product also features a creatine blend, including creatine monohydrate and micronized creatine monohydrate, to fuel high-intensity exercise and support muscle protein synthesis.

For enhanced strength and stamina, the Power Plus Blend in Mass XXX includes MyoTOR, an herbal blend clinically proven to improve muscle strength with half the exercise in as early as 2 weeks.* The formula also features a creatine precursor amino blend, including L-Arginine, L-Glycine, and Micronized L-Methionine, which are essential for creatine synthesis.

Micronized amino acids like L-Glutamine, L-Arginine, and L-Leucine are also included to support protein synthesis, muscle recovery, and fuel performance.* Unlike most mass gainers with proprietary blends, Mass XXX is certified Banned Substance Tested, ensuring the formula is designed to help users gain mass without compromising their goals.

For best results, Mass XXX should be used 1-2 times daily. On training days, one serving should be consumed post-workout, while on non-training days, one serving can be taken first thing in the morning or between meals as needed. With a high-calorie diet and appropriate strength training program, plus 1-2 servings of Mass XXX per day, users can expect to see weight gain and muscle growth, as the scale starts to move.

Whether you're a man or a woman, GNC AMP Mass XXX can support your muscle growth and performance goals.* Consistency and proper training are key, but with the clinically proven ingredients in Mass XXX, you can feel confident that your hard work is paying off, as you become bigger, stronger, and fitter.
